When a former member of the radical protest/terrorist organisation the Weather Underground (Sarandon) turns herself in to the FBI, Ben Shepard (LaBeouf), an aggressive young journalist, starts searching around for leads on the other members. Before long Ben uncovers Jim Grant (Redford) a former Weatherman - a fugitive wanted for murder. After living for more than 30 years under a false identity, Grant must now go on the run.
